"If it weren't for Facebook, then this wouldn't have happened in the whole beginning," she told Channel 3's Sara Shookman.

Prentice Dietrich-Smith died July 1, just hours after he was stabbed in the street outside his Euclid home. The accused killer, Christopher Dowen, now faces charges for murder, felonious assault and tampering with evidence.

Dietrich says Facebook messages like this one she provided show a fight that escalated to violence that left her son dead.

"This was not something that happened in a snap decision," she said. "I honestly believe that. There's no way for me to look at it any other way."

Dietrich is hoping for stiffer charges for a murder she believes was premeditated and justice against all those she believes were involved.

WKYC asked Euclid police and Cuyahoga County prosecutors, but they wouldn't comment on the case, saying they were not taking any chances to jeopardize the prosecution.

"This was a stupid fight over a girl where a kid had so much anger and rage that he carried out what he said he was going to do," said Dietrich.

Dowen pleaded not guilty to the charges and posted $100,000 bond, cash or surety, and he's now on house arrest awaiting a December trial.

"My son is on my mind all the time. He was a huge part of my life and it got taken away," said Dietrich. "And this kid is at home. I don't understand."

Prosecutors say they are still investigating the case as they prepare for trial but wouldn't elaborate on seeking additional charges.
